The Network is designed to be a collaborative approach, since one of the Sage Sayings is "I know how much damage a solo tax policy economist can do, without teaming with tax lawyers, tax accountants, statisticians, and industry specialists."

The Founding Members of the Tax Sage Network are Bob Cline and Tom Neubig. They have over 80 years of tax policy experience working in academia, governments, the private sector and an international research organization. The Network provides an opportunity to share some relevant experiences as well as comments on current tax policy issues.
